For identification, we use pre-determined variation in banks’ liquidity coverage ratio (LCR) in a difference-in-differences setup. Granular instrument-level data allow us to carefully control for any observable and unobservable time-varying factors at the creditor, instrument type, and macroeconomic levels. We find that banks with greater LCR exposure see a steeper decline in their wholesale funding costs.
